Abstract

本实用新型公开了降压降噪V型调节球阀,它包括阀体(6)、阀座(2)、降压降噪V形调节球体(4)、阀杆(5)和阀盖(1),阀盖(1)经密封圈(3)安装在阀体(6)上,降压降噪V形调节球体(4)、阀座(2)安装阀体(6)的阀腔内,阀杆(5)连接降压降噪V形调节球体(4);降压降噪V形调节球体(4)的一侧上开有足够的V形孔(8),同时开有许多曲折小孔(7),V形孔(8)与曲折小孔(7)相通。本实用新型设计足够的V形孔及曲折小孔保持低的流速来实现流量调节及压力逐渐降低,避免了介质高速流动及开度百分之三十时无法调节现象,以减少对下游阀座的压力,降低噪音,方便拆卸或维护,提高了调节性能,延长了使用寿命。

Description

降压降噪V型调节球阀
技术领域
本实用新型属于通用机械阀门制造技术,具体涉及一种降压降噪V型调节球阀。
背景技术
现有的球阀,主要有阀体、阀座、球体、阀杆、阀盖等组成,其球体常见的是如图1所示的O形口结构,这种结构的缺点是不能降低压力、减小噪音、控制流速,在开度30%时无调节变化,调节性能极差。
发明内容
本实用新型的目的在于:提供一种降压降噪V形调节球阀,避免高压差、噪音大、流速高及调节性能极差现象,它适用于高压差管路降低压力、控制流速、减小噪音及流量调节。
本实用新型的技术解决方案是:它包括阀体、阀座、降压降噪V形调节球体、阀杆和阀盖,阀盖安装在阀体上,降压降噪V形调节球体经阀座安装阀体的阀腔内,阀杆连接降压降噪V形调节球体;其特征在于:降压降噪V形调节球体的一侧上开有足够的V形孔,同时开有许多曲折小孔,V形孔与曲折小孔相通。
本实用新型相比现有技术的有益效果是:它能有效地改善降低高压差、控制高流速、减小噪音,在小开度时也能实现流量精确调节,介质通过曲折小孔逐渐降压减速,以减少对下游阀座的压力,提高了产品使用寿命,减小噪音保护环境,与普通的球体具有互换性同样可以很方便地拆卸或维护。
附图说明
图1是现有O型球体结构示意图。
图2是本实用新型的降压降噪V形调节球体结构示意图。
图3是图2的剖视俯视图。
    图中:1阀盖,2阀座,3密封圈,4降压降噪V形调节球体,5阀杆,6阀体,7曲折小孔,8V形孔。
具体实施方式
如图2、3所示,它包括阀体6、阀座2、降压降噪V形调节球体4、阀杆5和阀盖1,阀盖1经密封圈3安装在阀体6上,降压降噪V形调节球体4、阀座2安装阀体6的阀腔内,阀杆5连接降压降噪V形调节球体4;其特征在于:降压降噪V形调节球体4的一侧上开有足够的V形孔8,同时开有许多曲折小孔7,V形孔8与曲折小孔7相通。
